CAR-WINDOW.

SPECIFICATION forming part of Letters Patent No. 396,585, dated January 22, 1889.

Application filed May 31 1888.

T aZZ whom, it may concern:

Be it known that I, FRANK B. MALLORY, a citizen of the United States, residing at Flemington, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Car-Ventilating WVindows; and -I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in car-window sash-frames which are capable of being slid up and down for the purpose of coni 5 trolling the admission of fresh air into the car,

such frames being provided with hinged inner glazed sashes which can be swung out to an oblique position for the purpose of ventilating the car and deflecting sparks andsolid particles of matter; and my said improvement consists in the combination, with up and down sliding sashes of car-windows on both sides of a car, of two series of reversely-adjustable hinged glazed inner frames, in such a manner 2 5 that one series of the hinged inner frames on both sides of the car can be adjusted to proper 'oblique positions relatively to the sides of the car for ventilation of the car and deflecting and exclusion of sparks and solid matters while it is running in one direction, and the other series adjusted in proper reverse oblique positions for the same purpose while-the car is running in an opposite direction, and thus the car ventilated and sparks, 850., ex-

3 5 eluded on both sides of the car at the same time, whatever may be the direction in which the car is running.

In the accompanying drawings, Figure 1 is a side view of a portion of the inside of a car,

40 showing two of my improved sliding car-ventilating windows, the swinging portions being shown closed. Fig. 2 is a horizontal section of Fig. 1 on the line 00 00, one of the swinging portions being open and the other closed.

The dotted lines illustrate how the swinging portion, which is shown closed, can be swung outward at an angle. Fig. 3 is a horizontal section showing a sliding sash with two swinging portions and one of the swinging portions Fig. 4 is a similar View to Fig. 3, but showing one of the swinging por- $erial No. 275,547. (No model.)

tions moved outward to suit a reverse direction of movement of the car. A

In carrying out my invention I either make sashes A, as shown in Figs. 1 and 2, with a single swinging frame portion, A, separated by portions or of the car-body B, and arrange alternately the hinges or pivotal connections I) of each pair of the swinging portions A of the sashes upon the frame portionsc of the sliding sashes, so as to be in the relation shown to portions to of the car-body, and thus provide for forming with the swinging portion of one sash A an opposing and deflecting surface when the car is moving in the direction of the arrow 1, and an opposing and deflecting surface with the swinging portion of another sash when the car is moving in the direction of the arrow 2, as illustrated. by dotted lines; or I make, as in Figs. 3 and 4, each sliding sash A with a vertical central bar, d, and provide two swinging glazed portions, A within said sash, one portion on each side of the said bar, and hinged to a vertical part of the frame.

portion 0, and thus provide for forming arresting and deflecting surfaces with a single sliding sash, such surfaces, respectively, being adapted by the angle formed with the car-body to the respective direction in which the car is being moved. The sliding portions 0 of the sashes are fitted in guides f of the car, as shown, or in any other suitable manner, and the swinging portions A or A have their hinges or pivotal connections fastened to the inner vertical side piece or pieces of the said sliding portions, as shown in either Fig. 2,3, or 4, so as to swing outward at any desired angle with respect to the body of the car, as

illustrated in full and dotted lines in said figordinary fastenings-such as hooks and keep ers or pin s-may also be applied to said swinging portions and the car-body for holding the same in their closed position.

From the foregoing description it will be seen that the sashes can be raised and lowered for ventilation and other purposes, as usual, and that the glazed swinging portions can be swung out while the sashes are down for the purpose of deflecting cinders and affording ventilation. The action of the ventilating-window is, when the swinging portions of the sashes are swung out to form an angle with the car-body, to arrest and deflect the heavier particles of matter-such as cin ders and dust-and to admit fresh currents of air by the suction caused by displacement of the air by the car in rapid motion, the air for ventilation rushing in between the inner edge of a vertical. bar of the sliding portion of a sash and the outer free edge of the swinging portion of the sash, as indicated by the arrows 3.

Under the construction shown in Figs. 1 and 2 every alternate window will be closed and every alternate window open when a car moving in either direction and being ventilated; but under the construction shown in Figs. 3 and i one half of a sash. will be closed and the other open when a car is moving in either direction and being ventilated.

I am aware that a sliding sash-frame having an inner swinging glazed frame for ventilation of cars is not new, and therefore do not claim the same specifically; but

\Vhat I do claim is I o r 1. The combination, with the up and down sliding sash-frames of car-windows on both sides of a car, of two series of reversely-swinging and separately-adjustable glazed frames hinged to the sliding frames, one series on both sides of the car being adjustable to oblique positions adapted to one direction of movement of the ear, and the other series-adjustable to reverse oblique positions adapted to an opposite direction of movement of the car, substantially as and for the purpose described.

2. The combination, with a single up and down outer sliding sash-frame of a car-window, of two inner glazed frames hinged, respectively, to the uprights of the outer sliding sash, and separately adjustable to reverse oblique positions relatively to the side of the car, substantially as and for the purpose described.

In testimony whereof I hereunto affiX my signature in presence of two witnesses.

FRANK B. )IALLORY.
